IMPROVEMENT IN PRUNING IMPLEMENTS.

Specification forming part of Letters Patent'No. [50.724, dated May 12,1874 application filed March 21, 1874.

To all whom 'it may concern:

Be it known that I, LEXOR B. SNOW, of Cleveland, Ohio, have invented aPruner, of which the following is a specification:

The object of my invention is to lessen labor and economize power in thework of pruning trees or vines; and it consists in a novel use ofpivoted braces for .connecting together the cutting-blades, as will behereinafter more fully described.

A description follows sufficiently clear and exact to enable'any oneskilled in the mechanical arts to construct and operate the device,reference bein ghad to the accompanying drawings.

In Figure 1, A and B are two convex steel cutting-blades, joined by twometallic pivoted braces, C and D, on each side, the braces being curvedslightly, so as to allow free motion. To the cutting-blades are attachedlevers or handles F a-nd G, either of wood or metal, crossing each otherlike ordinary shear-blades, but moving on four pivots, a, b, c, and d,at the extremities of the braces C and D.

Fig. 2 is the reverse view of the device with the blades closed.

The operation of the pruner is as follows:

`The handles F and G are extended, as in Fig.

l. The cutting-blades A and B are placed against the bongh or vine to beout oft', at E. The levers are brought together and the cutting-bladesclose, as shown in Fig. 2, working on the four pivots with a drawingstroke and increasing force until the bough is severed.

This device overcomes the tendency to slide 0E from, and obviates thenecessity for any contrivance to hold the blades against, the bough, asthe stroke is of such a nature as to clasp rmly and retain it until cntoft'. It acts with powerful and constantly-increasin g force, overcominga difficulty always experienced in cutting with blades working by leverpower on one fixed pivot, viz., the necessity for the employment ofgreatly-increased power near the end of the stroke.

I claim asmy invention- The combination, in a pruning implement, of theconvex cutting-blades A and B, working on the four pivots a, b, c, andcl, and joined by the pivoted braces C and D, in the manner and for thepurpose set forth.

LEXOR B. SNOW.
